  • Publication number: 20160020845
    Abstract: A communication device includes antennas to receive a first signal from a remote device, wherein the first signal corresponds to a first operational mode. A baseband processor selects either a first operational mode for transmitting a second signal or a second operational mode for transmitting the second signal. When the second operational mode is selected the baseband processor transforms the phase-related information corresponding to the first operational mode to transformed phase-related information corresponding to the second operational mode. The antennas transmit the second signal to the remote device in accordance with the transformed phase-related information corresponding to the second operational mode.

    Abstract: A method and network device provides port scheduling for data ports in the network device. The network device may assign data ports of the network device into port groups according to port characteristics of the data ports. The network device may schedule processing time slots for active data ports by determining a selected port group based on group selection parameters. The network device may then determine a selected data port from the selected port group using port selection criteria. The port selection criteria may maintain minimum and maximum packet spacing requirements for the data ports of a port group. The network device may also maintain an active ports list to disqualify inactive data ports from selection.

  • Patent number: 9239600
    Abstract: Methods and systems for supplying power to multiple voltage islands using a single supply source are disclosed. Aspects of one method may include providing power to a first of a plurality of voltage islands, and individually controlling providing of power to each of a remaining portion of the plurality of voltage islands. For example, when an electronic system is first powered on, a low current voltage source may be used to supply power to a primary voltage island. As a higher current voltage source becomes available, power derived from the higher current voltage source may be provided to the primary voltage island and to secondary voltage islands. Power to each of the secondary voltage islands may be, for example, individually controlled via a power MOS transistor. The power MOS transistor may also be configured to allow a faster blocking time than unblocking time.

  • Publication number: 20160013908
    Abstract: Pilot tones are included within symbols (e.g., orthogonal frequency division multiplexing (OFDM) symbols) transmitted between wireless communication devices. The pilot tones occupy fewer than all tone locations in any given symbol, and the pilot tones occupy different respective locations within different symbols. Generally, these traveling pilots are assigned to different respective tone locations in different symbols. In total, the pilot tones did not cover every single tone location within the symbols used to convey information between devices. Considering for example, when pilots occupy fewer than all tone locations, even among multiple symbols, a device may perform interpolation to generate a pilot tone estimate corresponding to a tone location not occupied by pilot tone within any symbol. Also, power or magnitude of the pilot tones themselves may be boosted or amplified relative to power magnitude of other tones within such symbols.
